* Attempt to improve the logic for automatically sizing partitionsIan Dowse2005-08-141-5/+62
| | | | | | | | | | | | | | | to take into account the new default of starting the first partition after the boot blocks instead of at sector 0. If you used automatic sizing when the first partition did not start at 0, you would get an error that the automatically sized partition extended beyond the end of the disk. Note that there are probably still many more complex cases where automatic sizing and placement will not work (e.g. non-contiguous or out of order partitions). Notes: svn path=/head/; revision=149061
* Fix the derivation of the GEOM name from the specified device name byRalf S. Engelschall2005-01-071-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | complementing the existing special case of a not existing /dev prefix with the recognition of an already existing /dev prefix. This implicitly solves the following two issues related to working on GEOM devices /dev/foo/bar (which have the GEOM provider name "foo/bar") with the expected commands like "bsdlabel /dev/foo/bar": 1. the error "Geom not found" when trying to write or edit the BSD label (because previously the incorrect GEOM name "bar" instead of "foo/bar" was derived from "/dev/foo/bar"). 2. the multiple times reported "magically introduced" partition offset of 63 blocks and the resulting errors like "partition extends past end of unit" and "partition c doesn't start at 0!". This implicitly resulted because bsdlabel(8) determines the "MBR offset" via GEOM and (intentionally) silently falls back to an offset of 0 if it could not be queried (which is the case if the name was incorrectly derived). Usually (at least on PCs) the offset for the first slice is 63 blocks and bsdlabel(8) automatically subtracts them from the absolute offsets in the read on-disk BSD label, resulting in the display of an effective offset of 0. If the GEOM query fails, the assumed offset of 0 is subtracted and an incorrect effective offset of 63 is displayed and tried to be worked upon.

Allowing the installation of labels addressing as much of the disk as possiable may be a useful addition in some situations, but this was easy to implement and should reduce confusion.
